Paranoia inhibits chaining of multiple #having statements on an AR::Relation

[moxie]

class Person < ActiveRecord::Base
  acts_as_paranoid
end

>  Person.group(:name).having("count(id) > 1").having("count(id) < 1").to_sql
=> "SELECT `people`.* FROM `people`  WHERE `people`.`deleted_at` IS NULL GROUP BY name HAVING count(id) > 1"

upon removing acts_as_paranoid from the model:

>  Person.group(:name).having("count(id) > 1").having("count(id) < 1").to_sql
=> "SELECT `people`.* FROM `people`  GROUP BY name HAVING count(id) > 1 AND count(id) < 1"

I realize the #having statements used here are nonsensical, but hopefully this demonstrates the point. Please let me know if there is anything else I can do to help with this issue. I haven't been able to identify anything in the paranoia implementation that would cause this... but I don't really know how deep scopes, unscoped, etc goes.

Edit: I also should have specified this is with paranoia 2.0.2 and Rails 4.0.0. I did also test against Rails 4.0.3 because initially I thought it might have been an ActiveRecord issue, but the same behavior occurred there.

Apparently this is a known Rails issue where default_scopes are invloved. rails/rails#13965
